Single Phase Smart Power Meter which is a kind of single-phase two-wire (that is, AC 220V line) power consumption measurement device, generally used in residential households, to measure the overall energy consumption of household electrical equipment, as the basis for charging by the power department. Single Phase Smart Power Meter has the advantages of simple structure, convenient use and accurate measurement, but in the process of use, it is necessary to pay attention to the reasonable selection of specifications and correct wiring to ensure its normal operation and avoid safety accidents.
The development of Single Phase Smart Power Meter can be traced back to the end of the 19th century. Initially, electricity meters were mainly used to measure current and voltage, not electrical energy. In 1889, Westinghouse, a German, invented the world's electricity meter for measuring current and voltage. By the end of the 19th century, the demand for electricity gradually increased, and people began to realize the need to measure the consumption of electricity. The original single-phase electricity meter was an inductive watt-hour meter, and with the development of power electronics, by the beginning of the 21st century, electronic energy meters gradually replaced inductive energy meters. Electronic electricity meters have the advantages of high precision, powerful functions and stable performance, and can measure a wider range of power parameters, such as active power, reactive power, power factor, etc.
Single Phase Smart Power Meter can measure all kinds of power data, and according to market demand and application scenarios, single-phase anti-tamper electric energy meters, single phase prepaid energy meters, single-phase multi-function electricity meters, single-phase Internet of Things energy meters, single-phase smart meters, etc. are produced.
In terms of installation methods, Single Phase Smart Power Meter include din-rail Single Phase Smart Power Meter, suspended Single Phase Smart Power Meter, embedded Single Phase Smart Power Meter, single-phase ANSI meters, etc. Why are there so many installation forms? This is related to the installation environment and national standards of Single Phase Smart Power Meter use scenarios. In the selection of Single Phase Smart Power Meter not only to consider the installation form, but also to clearly select the specifications of the electric energy meter is mainly voltage, current, in the selection of current capacity need to understand the max load power of the measured line, the max current range of Single Phase Smart Power Meter must be greater than the max load current, so as not to cause Single Phase Smart Power Meter measurement inaccurate or overload damage.
Single Phase Smart Power Meter has a wide range of applications in daily life and industrial production, such as residential areas, rental houses, hotel apartments, shops, dormitories, etc. The origin of Single Phase Smart Power Meter is closely related to the development and demand of electricity, it is an important power measurement equipment, which provides basic support for power management and power monitoring, and plays an important role.
